How do you make a permanent magnet?
Manipulate a ferromagnetic metal so that all the domains are unaligned
Manipulate a ferromagnetic metal so that all the domains are aligned
Manipulate a ferromagnetic metal so that all the domains are pointing randomly
Magic
What would happen if you cut a magnet in half?
You would create two smaller magnets
You would cause the magnet to stop functioning as a magnet
You would create two polarized half-magnets (one north piece and one south piece)
Half would be a magnet and the other half would stop being a magnet
Magnetic fields flow:
From the magnetic south pole to the magnetic north pole
From the magnetic north pole to the magnetic south pole
From the magnetic north pole back to the magnetic north pole
From the magnetic south pole back to the magnetic south pole
When a charge enters a magnetic field, the magnetic force on the charge is at its maximum value when:
The charge enters parallel to the field
The charge enters the field at a 45 degree angle
The charge enters perpendicular to the field
The angle is irrelevant
The right hand rule is used for:
Positive Charges
Negative Charges
Neutral Charges

Magnetic fields are caused by the flow of:
Protons
Nuetrons
Electrons
Alpha particles
Like Electric Field lines, the Magnetic Field lines go opposite the flow of electrons.
True
False
A current travels through a wire as shown below. What direction is the magnetic field created by the current?
Up
Down
Clockwise
Counterclockwise
Which of the following would increase the magnitude of the magnetic field on the charge shown in the diagram? Check all that apply.
Move the charge further away from the wire
Move the charge closer to the wire
Increase the current
Decrease the current
Magnetic Flux is measured in:
Volts (V)
Newtons (N)
Teslas (T)
Webers (W)
Which of the following would result in a change to the magnetic flux? Check all that apply.
Change the strength of the magnetic field
Change the area
Change the material used for the wire
Change the angle of the wire in relation to the magnetic field
Compasses work because they have a magnet in them. The magnet is attracted by the Earth's magnetic field and thus points North. This implies:
The Earth's geographic north pole is also the magnetic north pole
The Earth's geographic north pole is the magnetic south pole
The Earth's magnetic north pole is at the equator
The Earth's magnetic north pole is weaker than the compass's north pole
The process of using a magnetic field to create an electric current is known as:
Magnetic Flux
Aligning domains
Magnetic Induction
The electromotive force (emf)
